COIN-OPERATED GASOLINE PUMP.

Application filed September 2, 1926. Serial No. 133,235.

g The present invention relates to dispensing apparatus, particularly for liquids such as gasoline and other fuels used particularly by motor vehicles.

An object of this invention is to provide a dispenser or pump of this character, which is automatic in operation, so that upon the insertion of a coin of predetermined value the mechanism may be set in motion so as to deliver a commensurate proportion of the fuel or other liquid to be dispensed.

A further object of this invention is to provide a pump or dispenser of this character, which may be utilized for delivering different quantities of the liquid in accordance with the character of the coin inserted so that when a small coin is inserted, a predetermined amount of the liquid may be dispensed and when a larger coin is inserted, a proportionately greater amount of the liquid may be dispensed.

The invention also aims at the provision of a mechanism of this character wherein may be, employed bucket weighing features 5 instead of the displacement method usually employed and wherein this bucket weighing feature is adapted to the measuring out of different quantities in accordance with coins of different values.

WVith the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts through.- out the several views,

Figure 1 is a vertical section taken through a dispensingdevice constructed according to the present invention.

Figure 2 is a detail enlarged sectional view taken through the coin receiving and tripping mechanism showing the mechanism in posit-ion with the balancing bucket located as shown in Figure 1.

Figure 3 is a top edge View of the same.

Figure 4 isa vertical sectional view taken through the coin receiving mechanism showing the coin in initial position as illustrated in Figure 2 but with the first check released and the second check in position to stop the coin intermediate the chute.

Figure 5 is a similar view showing the next operation of the coin mechanism with the second trip released and illustrating the coin in its initial movement toward its last position, and

Figure 6 is a like view showing the coin mechanism in position to release the coin from its third position.

Referring to the drawings, 10 designates a casing of any suitable type provided at its upper end with a receptacle 11 having- ,ments on the pivot 14 by a stop 17 which is carried within the receptacle 11.

A fluid feed pipe 18 passes up through the base 19 of the apparatus and to a pump 20 operated by an electric motor 21. From the pump 20 a supply pipe 22 rises through the casing 10, through the bottom 13 and into the top of the receptacle 11 and has a discharge opening 23 immediately over the pivot let, so as to discharge the incoming liquid into either end of the bucket 15, according to its position. The base 19 may be secured by bolts 24 to a cement base or the like. The electric motor 21 has one pole secured to a current feed wire 25. The other pole of the motor 21 is connected to a wire 26, which is carried upwardly in the casing 10 to a suitable point and is connected by bolts 27 to one side of a coin control mechanism utilized for closing a circuit through the motor 21 by the inserted coins. The other side of the coin mechanism is connected by a current feed wire 28. which is carried from a. connecting bolt 29 downwardly through the casing 10 in proximitytothe current feed wire 25 where the two may be carried off in a conduit 30 to any suitable source of current supply.

The casing 10 is provided at a suitable height with a coin receiving slot 31 adapted to receive coins of different sizes, and the slot 31 is in register with a chute 32 extending inwardly and downwardly from the slot 31to the coin checking and circuit closing mechanism.

As best shown in Figures 2 to 6, the coin controlling mechanism comprises a frame having a passage-way 34 therethrough of sufiicient width to receive the largest coin to be inserted in the mechanism. At one side of the slot 34 is'positioned a double,

stance comprises a bar having an upper arm 36 and a lower arm 37, the arms extending through the frame 33 and lying flush with the inner wall so that-a coin 38 may come into contact first with the arm 36, and sub sequently with the arm 37. The frame 33 is of electric non-conducting material or is insulated from the bar The frame 33 may he made in one or more parts and is clamped together by the bolts 27 and 29. At the other side of the slot 34 is placed a pair of latch levers and 40, which are substantially of bell crank form, the lever 39 having a relatively short projecting end and arranged at the top of the frame 33, while the lever 40 has a relatively long projecting end and is disposed toward the lower end of the frame 33. Both of the levers 39 and 40 are arranged to project into the slot 34 and are also mounted so that they may be swung out of the slot 34 to permit of the free passage of the coins 38 therethrough. A link 41 connects the outer ends of the levers and 40 together to hold the same in parallel relation and effect their simultaneous movement. The levers 39 and 40are pivoted at their angle portions upon the bolts 27 and these levers 39 and 40 provide movable contacts adapted to engaged the coin 38 at difiierent times during its progression through the slot 34. An intermediate latch 42 is pivoted on the frame 33 between the levers 39 and 40 and has a projecting portion and also a heel portion 43 adaptedto be engaged by the projecting end of the upper lever 39 when the latter is swung upwardly, so as to release the coin 38. The heel of the lever 43 is offset upwardly so as, to engage the lever 39 and swing the latch lever 42 out into the slot 34 and into the path of the coin 38. It will be noted, however, that both the latch 42 and the upper lever 39 project only a slight distance into the slot 34, so as to catch and hold coins of large denominations. The link 41 has a pin 44 which engages in the slotted end 45 of an operating lever 46 pivoted at 47 on the bracket 48 carried by the frame 33. The lever 46 'is connected at its outer end to a wire 49 of usual construction, which has a tube 50 secured to a bracket 51 carried on the inner side of the casing 10, the tube 50 extending upwardly and through the bottom 13 to a point adjacent the lower end of the rocking frame 16. The upper end of the wire 49 is secured to the lower end of the frame 16, and as the lower end of the frame 16 is spaced from the pivotal support 14 oi the frame, the wire 49 is moved back and forth through the tube 50 as the bucket 15 is over balanced from side to side.

In operation, a coin is inserted in the slot 31 and is guided by the chute 32 into the slot of the coin controlling apparatus. If the coin 38 be large, the coin will fall into the position, shown in Figure 2, or against the upper lever 39. The current will therefore be closed through the bar and lever 39, so that the motor will be operated and. the gasoline or other liquid will be pumped upwardly through the pipe 22 and will flow from the outlet 23 into the bucket 15. liquid is deposited in the bucket 15, the

latter will be over-balanced, so as to swing over in the receptacle 11 and dump the liquid so deposited in the bucket. The liquid will flow down the bottom 13 and out through the nipple12 and nozzle 52. As the bucket 15 is overbalanced, the Wire 49 forces the operating lever 46 downwardly and swings the link 41 upwardly with the result that the upper lever 39 is retracted from the slot 34, as shown in Figure 4, and at the same time the intermediate latch 42 is projected outwardly into the slot 34, so as to catch the coin 38 after it has been released from the lever 39. As soon as the coin 38 drops down upon the second latch 42, the circuit is broken and the pumping action of the gasoline momentarily stopped until the bucket 15 assumes its opposite position and is ready to receive another charge of the liquid.

As the bucket reaches its second position, the wires 49 operates the lever 46 so as to swing the lovers 39 and 40 downwardly to release second latch 42 and free the coin 38, and at the same time to project the lower lever 40 into the slot 34 to catch the coin 38, as shown in Figure 5, and maintain the coin 38 against the lower arm 37 of the con tact bar 35 and complete the circuit a second time so as to fill the opposite side of the bucket 15. As soon as the bucket 15 is filled:

at its opposite side it will be overthrown by the weight of the liquid and the wire 49 will be operated to swing the lever 40 and release the coin 38, as shown in Figure 6.

There will thus be a checking of the coin to first close the circuit and fill one side of the bucket, a second checking of the coin until the bucket has dumped its contents and is in position to receive the second charge, and finally a third checking of the coin in order to close the circuit and fill the op posite side of the bucket.

hen the coin is ofless size it will pass l'recly down to the lower latch lever 40, where it will be held until one side of the bucket is charged with the liquid and is over-thrown. I i

The larger coin thus delivers twice the amount of the smaller coin, and the operation is effected by the same mechanism which delivers one quantity of the liquid by merely repeating its operation.

It is obvious that various changes and modifications may be made in the details When a sufiicient amount of of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
